Managing Path Selection Policy Plug-Ins with esxcli storage nmp psp
You can use esxcli storage nmp psp to manage VMware path selection policy plug-ins included with the
VMware NMP and to manage third-party PSPs.
I When used with third-party PSPs, the syntax depends on the third-party PSP implementation.
Retrieving PSP Information
The esxcli storage nmp psp generic deviceconfig get and esxcli storage nmp psp generic pathconfig
get commands retrieve PSP conguration parameters. The type of PSP determines which command to use.
n
Use nmp psp generic deviceconfig get for PSPs that are set to VMW_PSP_RR, VMW_PSP_FIXED or
VMW_PSP_MRU.
n
Use nmp psp generic pathconfig get for PSPs that are set to VMW_PSP_FIXED or VMW_PSP_MRU. No path
conguration information is available for VMW_PSP_RR.
To retrieve PSP conguration parameters, use the appropriate command for the PSP.
n
Device conguration information.
esxcli <conn_options> storage nmp psp generic deviceconfig get --device=<device>
esxcli <conn_options> storage nmp psp fixed deviceconfig get --device=<device>
esxcli <conn_options> storage nmp psp roundrobin deviceconfig get --device=<device>
n
Path conguration information.
esxcli <conn_options> storage nmp psp generic pathconfig get --path=<path>
n
Retrieve the PSP conguration for the specied path.
esxcli <conn_options> nmp psp pathconfig generic get --path vmhba4:C1:T2:L23
The esxcli storage nmp psp list command shows the list of PSPs on the system and a brief description of
each plug-in.
Setting Configuration Parameters for Third-Party Extensions
The esxcli storage nmp psp generic deviceconfig set and esxcli storage nmp psp generic pathconfig
set commands support future third-party PSA expansion. The setconfig command sets PSP conguration
parameters for those third-party extensions.
N The precise results of these commands depend on the third-party extension. See the extension
documentation for information.
Use esxcli storage nmp roundrobin setconfig for other path policy conguration. See “Customizing
Round Robin Setup,” on page 105.
You can run esxcli storage nmp psp generic deviceconfig set --device=<device> to specify PSP
information for a device, and esxcli storage nmp psp generic pathconfig set --path=<path> to specify
PSP information for a path. For each command, use --config to set the specied conguration string.
